Forbes Marshall is an ISO 9001 certified company that distributes the R- Series Flow Monitors Providing Frequency and an Analog Linear Output in India. The Flow Monitors Providing Frequency and an Analog Linear Output is based on the dependable differential pressure principle. This principle offers simplicity and comes at relatively low cost. The R-series Flow Monitors Providing Frequency and an Analog Linear Output has a robust and sturdy design. It combines the mechanical reliable function with an electronic circuit board providing electrical outputs linear to flow of liquids or gases. The design of R-series Flow Monitor gives highly repeatable output signals and often excludes the need for using more expensive flow meters. The frequency output is linear to flow between 200-1000 Hz and the analog output is a linear current 4-20 mA. This Flow Monitors Providing Frequency and an Analog Linear Output can serve as a flow transmitter due to lack of local indication. The R-series, as distributed by Forbes Marshall comes in two measuring ratios designated as R2 and R5, which means that the R2 has a measuring span of 1:2 and the R5 has a span of 1:5. The R- Series Flow Monitors Providing Frequency and an Analog Linear Output can monitor both liquids and gases.
